Sorry, command-not-found has crashed!
新安装了一台ubuntu server
安装时用中文安装的，之后命令行下各种乱码，最后也不知道是修改哪里造成的
每次执行一次错误的命令就会报错：（报错信息如下）
Sorry, command-not-found has crashed! Please file a bug report at:

Please include the following information with the report:
command-not-found version: 0.3
Python version: 3.3.1 final 0
Distributor ID: Ubuntu
Description: Ubuntu 13.04
Release: 13.04

Exception information:
unsupported locale setting
Traceback (most recent call last):

locale.setlocale(locale.LC_ALL, '')
File "/usr/lib/python3.3/locale.py", line 541, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting
当然后来安装了zsh后解决了，但是vi里面中文还是显示乱码
搜索了下，说是编码有问题
解决方法：
bash下执行命令：
export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
sudo locale-gen en_US.UTF-8
sudo dpkg-reconfigure locales
解决！
sudo cd和sudo ll命令报错问题：http://www.linuxdiyf.com/linux/2265.html
